Abstract:

An investigation was made of a special organization of hardware to solve a two-dimensional heat conduction problem. The investigation indicated that a speed increase of seven times is possible over the normal sequential method used in solving the problem on the IBM 7090. The speed-up is achieved by use of a parallel computation procedure and the elimination of bookkeeping operations which alone allows a speed increase of better than two and the use of higher speed circuitry which is already beyond the laboratory stage. Further speed increases are possible through increased data transfer rates, multiple parallel V units and the addition of input-output equipment in V . All analyses were performed using average times for the various atomic processes. An examination of the possible maximumminimum range of operation times indicate that a more detailed analysis should consider the queue problem which may result. A method for reorganizing V at electronic switching speeds wa described. This method is sufficiently general t be useful in high-speed switching bet een selected problem types. Author
